Neil Robertson is a baker at Bellagio that has been on www.e-gullet.com discussing the opening of the bakery.  He has fascinating pictures of the bakery offerings, as well as the chocolate fountain.  You do have to read through a lot of interesting discussions. http://forums.egullet.org/index.php?showtopic=59798&st=0 The actual picture of the fountain does not appear until page 3 of the discussion.
